Answer to Question #26296 in C++ for red rose

Question #26296
An angle is considered acute if it is less than 90 degrees, obtuse if it is greater than 90 degrees, and a right angle if it is equal to 90 degrees. Using this information, write a C++ program that accepts an angle, in degrees, and displays the type of angle corresponding to the degrees entered.


A student’s letter grade is calculated according to the following schedule:

Numerical grade Letter grade

Greater than or equal to 90 A

Less than 90 but greater than or equal to 80 B

Less than 80 but greater than or equal to 70 C

Less than 70 but greater than or equal to 60 D

Less than 60 F

Using this information, write a C++ program that accepts a student’s numerical grade, converts the numerical grade to an equivalent letter grade, and displays the letter grade.
Expert's answer
#include <iostream>

using namespace std;

int main()
{
/* Ask the user to enter an angle in degrees */
double angle;
cout << "Enter an angle in degrees: ";
cin >> angle;

/* Normalize the angle if it's bigger than 360 degrees */
while (angle > 360)
angle -= 360;

/* Print the type of the angle */
if (angle == 90)
cout << "The angle is right." << endl;
else if (angle < 90)
cout << "The angle is acute." << endl;
else
cout << "The angle is obtuse." << endl;
return 0;
}
